Continuing the trend seen in recent years, more and more smelters are recognising
the benefits of using the VHE
Stimir Hall Effect Cathode Current Meter. Recent orders include Valesul,
Dubai Aluminium and Companhia Brasileira de Alumínio .
The VHE Cathode Current Meter is a specialised portable ammeter and makes use
of the Hall Effect. The instrument is lightweight and easy to operate. The conductor
current is instantaneously displayed on the integral backlit screen.
The U-shaped sensor head does not need to go fully around the conductor, making
it both easier and quicker to take multiple measurements. A screen icon indicates
low power remaining in the standard 9V alkaline dry cell. An over-temperature
warning protects against excessively heat.
Every Cathode Current Meter is customised to specific customer requirements
– the lance length and angle is configured for easy access, the probe
is dimensioned to suit the conductor, and the meter is scaled for the pot current.
VHE also manufactures an Anode Current Meter designed to measure the current
flowing in the anode rods using the volt drop principle. The lightweight instrument
instantaneously displays the cathode current on the integral meter.
